Coding and decoding in the Evolution of communication: Information richness and Referentiality |
Abstract | ||
---|---|---|
One of the most basic properties of the communicative sign is its dual
nature. That is, a sign is a twofold entity composed of a formal component,
which we call signal, and a referential component, namely a reference. Based on
this conception, we say that a referent is coded in a particular sign, or that
a sign is decoded in a particular referent. In selective scenarios it is
crucial for the success of any adaptive innovation or communicative exchange
that, if a particular referent a is coded in a particular signal s during the
coding process, then the referent a is decoded from the sign s during the
decoding process. In other words the referentiality of a signal must be
preserved after being decoded, due to a selective pressure. Despite the
information-theoretic flavour of this requirement, an inquiry into classical
concepts of information theory such as entropy or mutual information will lead
us to the conclusion that information theory as usually stated does not account
for this very important requirement that natural communication systems must
satisfy. Motivated by the relevance of the preservation of referentiality in
evolution, we will fill this gap from a theoretical viewpoint, by deriving the
consistent information conveyed from an arbitrary coding agent $A^v$ to an
arbitrary decoding agent $A^u$ and discussing several of its interesting
properties. |
